No Drawing. Application filed February 3, 1912, Serial No. 675,215.Renewed October 15, 1915." Serial To all whomz't may concern:

Be it known that I, CARLETON ELLIS, a citizen of the United States, andresident of Montclair, county of Essex, and State-of New Jersey, havemade certain new and useful Inventions Relating to Finish-Removers, ofwhich the following is a specification.

This invention relates especially to finish removers for the removal ofpaint, varnish or similar finish in which the inflammability of' thecompositions is completely or considerably suppressed as by theincorporation of chlorinated solvents, suitable heavy solvent materialsuch as benzyl alcohol being used in considerable proportion if desired.5'

Benzyl alcohol and many other similarly high boiling point benzylderivative finish solvent materials, such as benzyl acetate, carbolicbenzyl ester, cresylic benzyl ester, benzyl chlorid, benzaldehyde, andso forth, having solvent action on finish, may be advantageously used inremovers in which it is desirable to prevent or suppress inflammability.Such benzyl derivative finish solvent material may be used in theremover to as great an extent as 40 to 60 per cent. or more when desiredand give removers free from undesirably inflammable or explosive vaporswhen combined with suitable high boiling point solvents or whencarbon-tetrachlorid or other suitable inflammability suppressingchlorinated material is used. Suitable high boiling point solventmaterial for use in this connection may comprise phthalic methyl ester,phthalic ethyl ester, dichlornaphthalene, dichlorhydrin and solventnaphtha, preferably of the heavier grades, especially when fractionated.Solvent naphtha which is the third distillate from coal tar as usuallyprepared has a specific gravity of about .875 and a flashpoint of about80 F. and consists largely of xylol,

cumol and mesitylene, about 90% distilling .off at a temperature of 160C. Other penetrating solvents preferably having high flashpoint may beused, such for example, as petroleum naphtha free from kerosene andhaving a fiashpoint of 105 F. or so. The loosening solvent incorporatedshould be preferably the alcohols and the other loosening finishsolvents having a relatively high flashpoint and being substantiallywater immiscible in character so as to be relatively free from waterwhich minimizes I hydrolytic decomposition in the case of incorporatedchlorinated solvents. Besides benzyl alcohol, allyl and other finishsolvent alcohols are useful in this connection and of course ethylalcohol may be used in some cases, preferably in relatively smallamounts where the best inflammability suppressing results are desired.An illustrative remover of this character may comprise 30 parts ofbenzyl alcohol, 25 parts of benzyl acetate, 40 parts of coal tar solventnaphtha,

15 parts of carbon-tetrachlorid, 5 parts of hard parafiin Wax. Anotherillustrative composition may comprise mixed benzyl de-.

rivative finish solvent materials, such as 30 parts of benzyl alcohol,25 parts of benzyl acetate or of benzaldehyde, 40 parts of solventnaphtha, 5 parts of cresylic orcarbolic acid, 15 parts ofcarbon-tetrachlorid and 5' parts of hard paraiiin wax.

Another illustrative remover may comprise 10 parts of phthalic methylester, 35 parts of fractionated heaviest solvent coal tar naphtha, 30parts of benzyl alcohol and 25 parts of benzyl acetate.

Another illustrative composition may comprise 30 parts of cresylicbenzyl ester,

15 parts of phthalicmethyl ester, 20 parts benzyl rious classes of workand-2 to 5 per cent. or

more of various hard waxes or waxy bodies may also be incorporated ifdesired; pyroxylin and nitrated -or acetylated starches or gums may alsobe used as thickeners, preferably in connection with some wax.

' Another illustrative composition may comprise 40 parts of benzylalcohol, 40 parts of solvent naphtha and 5 parts of parafiin wax.

Another comprise l parts of benzyl alcohol, 40 parts of solvent naphtha,10 parts of carbolic or cresylic acid and parts of parafiin wax.

Another illustrative composition may comprise 40 parts of benzylalcohol, 25 parts of solvent naphtha, 15 parts of pine oil, 5 to partsof carbon-tetrachlorid and 5 parts of paraffin Wax.

Another illustrative composition may comprise 40 parts of solventnaphtha, parts of cresylic acid, parts of pine oil or of wood tar oilwhich may be deodorized by reducing heat treatment with hydrogen and 5parts of paraflin wax.

Another illustrative composition may comprise 50 parts of turpentine, 20parts of car bolic acid with or without parts of benzyl alcohol and 5parts of paraffin or ceresin.

' Another illustrative composition may comprise ethyl alcohol 30 parts,benzyl alcohol 30 parts, carbon-tetrachlorid 25 parts, nitrostarch 3parts and parafiin wax 3 parts.

Another illustrative composition may comprise ethyl or grain alcohol 40parts, carbontetrachlorid 40 parts, acetylated starch or gum 5 parts andceresin Wax 5 parts.

Another illustrative composition may comprise ethyl alcohol 12 parts,benzyl alcohol 25 parts, solvent naphtha 12 parts, pine oil 12 parts,carbon-tetrachlorid 15 parts and parafiin 5 parts.

Another-illustrative composition may comprise ethyl alcohol 45 parts,carbon-tetrachlorid 30 parts and ceresin wax 5 parts.

Another illustrative composition may comprise ethyl alcohol 30 parts,-carbon-tetrachlorid 20 parts, trichlorethane 30 parts, nitro-gum, suchas nitrated .gum arabic, nitrated gum tragacanth or other vegetable andresinous gums or nitrated starch 3 parts and paraifin 3 parts.

Another illustrative composition may comprise ethyl alcohol 30 parts,dichlorethylene 30 parts, pyroxylin 3parts and paraffin wax 3 parts.

- l The ethyl or grain alcohol referred to in the foregoing sevenformulas is preferably dehydrated as by drying commercial grain alcoholover quicklime for several days and then decanting the dehydratedalcohol from the lime. If desired also suitable antacid material may beincorporated with the alcohol such as 4 ounces of finely powderedbenzoate of soda and 4 ounces or so of carbolate T85 of soda for eachgallon and this modified illustrative composition may.

alcohol stock may be used in the foregoing formulas.

Another desirable illustrative composition may comprise 50 parts ofsolvent naphtha, 25 parts of carbon-tetrachlorid, 20 parts of amylalcohol, 5 parts of amyl acetate and 4 to 5 parts of parafiin or ceresinwax.
